Final answer:
The slope of the log-log graph is proportional to the exponent in the power law function, and the plot should be a straight line.
Step-by-step explanation:
In a log-log plot of a power law function y = a * x ^ n, the slope of the graph is proportional to the exponent n in the equation. Specifically, the slope represents the rate at which the dependent variable y changes with respect to the independent variable x. The shape of the log-log plot should be a straight line, indicating a power law relationship between x and y.
